Довелось мне как то поработать с особо параноидально-жадным клиентом. Было закуплено куча китайских камер и несколько регистраторов на 64 канала. Камеры все были подключены по Onvif, потому часть с них могла синхронизировать время с регистратором, а часть не могла. Весь зоопарк неплохо показывал, но вот время на камерах прыгало спустя неделю-вторую. А все из-за того что на объекте не было интернета или локального NTP сервера, зато был охранник который 24 часа долбился в монитор на компе. На предложение поставить хотя бы простой роутер с сим-картой чтобы отрабатывал как ntp сервер ответ был один — это небезопасно и вообще за это наказывают (клиент с Дубая). В общем решением стало установка ntp сервера на компе охранника. И если время сбивается он просто переводит его на компе, и все камеры показывают нужное время

NTP Download
Basic information on NTP can be found on our
NTP info page as well as in our
knowledge base articles.
The Meinberg NTP package provides a GUI setup program for Windows which installs the NTP service and associated executable programs that have been compiled from the original public NTP source code available at the
NTP download page at ntp.org.
The GUI installer also contains the corresponding HTML based NTP documentation, as well as the
libcrypto DLL from the
OpenSSL project,
which is required to create or check signatures of the NTP network packets, if the symmetric or public key authentication feature is used.
Unattended installation is also supported. Please see the
NTP Installer README
for help on how to use the installer.
Actually there a different stable NTP versions provided, plus some additional information:
- NTP package for current Windows versions (XP and later), with IPv6 support
- Outdated NTP package for Windows NT, Windows 2000, and newer, IPv4 only
- External Web Links
- NTP Cheat Sheet / Short Reference
- Linux driver for Meinberg plug-in radio clocks
For the Windows operating system there’s also an
NTP Time Server Monitor program
available which allows configuration of the local NTP service and graphical monitoring
of the local and remote NTP servers.
If you have any questions or feedback, please contact
ntp-support@meinberg.de.
NTP for current Windows versions (Windows XP and later), with IPv6 support
The current stable NTP version can be used with current 32 and 64 bit Windows versions (Windows XP and newer).
Beside the standard IPv4 network protocol it also supports IPv6.
Alternatively, there’s an older version available which can also be used on Windows 2000
or even Windows NT.
Note: The current setup program ntp-4.2.8p15a supersedes ntp-4.2.8p15 and ntp-4.2.8p15-v2.
It includes preliminary patches for some minor vulnerabilities, see
this KB page.
This package also includes the current openSSL libcrypto DLL v1.1.1t.
It is explicitly recommended to upgrade earlier installations to this version.

How to verify integrity of the downloaded file
Note:
If the NTP service fails to start after installation on Windows XP or Windows 7, the
Visual Studio Redistributable package my be missing,
althogh it should be available by default on all current Windows installations.
The 32 bit (x86) version of the redistributable is required even on 64 bit Windows systems.
The package is available from the Microsoft download page:
Go to Windows Download Center
Installation of the Redistributable Package (Screenshots)
NTP for Windows NT, Windows 2000, and newer, IPv4 only, without current security patches
This version of the NTP package is outdated but is still provided since it can also be used on Windows 2000 or even Windows NT.
It supports IPv4 only, but not IPv6. For current Windows installations the
current stable NTP version should be used which also contains current security patches.

NTP Short Reference (A4, 2 pages), English language. Contains short lists of the most important NTP
configuration parameters, command line options and file formats used by NTP, e.g. for the keyfile
or the statistic files that can be generated by ntpd (loopstats, peerstats, clockstats, sysstats).
Linux driver for Meinberg plug-in radio clocks
A Linux driver for Meinberg PC plug-in cards is available on our
driver download page.
That driver is only required for plug-in radio clocks. Radio clocks
which are connected via a serial interface are directly supported by
NTP.

When it comes to solving your time maintenance issues, Network Time System provides the answer.
This is powerful client/server software which enables you to create a virtually fail-safe synchronized time environment
for networks of all sizes and complexities. From those who use single site and small office networks (LAN) to those who employ
large enterprises (VLAN, VPN, and WAN) that include numerous domains and use complex routing techniques, Network Time System pulls everything together.
Basically, this means that Windows Network Time Server creates a custom source of precise time found in a corporate network environment which synchronizes every
machine and device in the company. The establishment of this time server or time client coordinates all activities on the
network so that there is no differentiation in terms of time synchronization. The advantages are significant when you consider networks of logging servers,
POS terminals, workstations, Kiosks and the like. By having everyone on the same time, you create greater efficiency in your company.
Products of Network Time System software:
There are a number of excellent features incorporated into this system, which makes time synching a powerful part of your business efforts.
32-bit & 64-bit Windows Support
Both the Server and Client are native 32 and 64-bit compiled executables and will run with all versions
of Windows from Windows 2000 up to Windows 10 and Server 2012.
Admin Control
This will allow or deny users to configure the Network Time System Client in a direct manner with the Network Time System Server interface.
Client/Server Architecture
You can set up a single or multiple time server units that are capable of overseeing thousands of time clients.
It includes workstations or NTP server, NTP client or SNTP compatible devices.
Custom Time Zone & Offset
Allows for customization of source time such as when received from an NIST Time server and distributed
to other time clients. You can keep the time synchronized by converting it to local time or using the UTC. This allows you to add or subtract
any number of seconds/minutes/hours from the source time so that you can create your own unique time offset.
Multi-Protocol Support
Network Time System supports the most widely used NTP/SNTP and NMEA 0183 as well as its own proprietary
time protocol for maximum flexibility.
Network-wide Deployment
You can deploy the Network Time System Client through Group Policy to all Windows-based computers in just
a few minutes time. In addition, the system itself is quite intuitive and easy to use making it very valuable to any small to large companies.
Powerful License Manager
You can install, move or delete your licenses whether they are original, additional or updates in an easy
manner using the built-in license manager. In addition, this feature will allow you to distribute as well as synchronize all of your licenses
across the network making updating a very simple matter.
Network Time System as handled through the NTP Server and NTP client for Windows
provides a valuable tool for synchronization of all devices on the network. The advantages of this system are considerable for companies of all sizes, from small to large corporations, download trial version today.
